I've been fighting with my bike for a couple days now and I think I'm ready to give in and ask for some help. My bike is a 2001 yz426. I just got it a week and a half ago, it was running well, and then all of a sudden stopped running so well. I've gone over a number of things on it... cleaned carb, new spark plug, changed the oil(&coolant). Eventually I remembered the day it started acting weird I had also messed with the timing belt tensioner. Long story short I think I tried to start the bike with the tensioner too loose and the timing chain slipped a tooth on one of the cams. So tonight I pulled it all apart and took a look and I could see that the timing marks definitely weren't lined up. From the left side of the bike, looking at the timing belt, I had to rotate the intake cam counter clockwise. From what I could see in my manual at TDC the "E" should be on the left side of both, and the marks on the outer edges of the cams should line up with the top of the engine. I actually had to move it 2 positions to get them to line up. Thought I had it for sure this time. Buttoned it all back up, pushed it outside, and still no luck. Before it would eventually start, and just not run well. Now it doesn't even want to let me through the whole kickstart stroke. I made sure to spin the engine slow a number of times first to make sure the valves were clearing the piston, and even if I pull in the decomp lever it'll let me spin the kickstart nice and easy, but when I get it in position and try to kick it'll go about 90 degrees and just stop like it built up a ton of compression. Any ideas?? I'm wondering if I should've only moved it one position instead of two, if that has anything to do with it. One thing I did notice that caught my attention was that when the marks on the gears were lined up, the lobes weren't pointing completely away from each other. The intake lobe was slightly angled up. I wouldn't have thought much about it, but I swear I saw a picture somewhere of the two of them pointing directly away from each other. Only problem is if they're pointed way, the dots on the gears won't be completely lined up. Well I guess the marks could still line up, they'd just do it lower. The only thing making this more complicated is that my bike has the Baja designs stator on it, so I have no way to pull off the side cover and just rotate the engine with a socket and use the mark to know when it's at TDC. I was just slowly rotating it by hand with the kickstarter and a straight piece of rubber in the spark plug hole to tell when the piston was at it's highest. I know that's not ideal, but I'm not sure what other way I'd be able to tell. So to cut the down to a simple question, should the cam lobes be pointing exactly away from each other when the piston is at TDC or are they slightly offset from each other??
